US Patent:

40193152, Apr 26, 1977

Filed:

Jun 20, 1973

Appl. No.:

5/371623

Inventors:

Robert A. Yannone - Aldan PA
James J. Shields - Philadelphia PA

Assignee:

Westinghouse Electric Corporation - Pittsburgh PA

International Classification:

F02C 910

US Classification:

60 3903

Abstract:

A gas turbine power plant is provided with an industrial gas turbine which drives a generator coupled to a power system through a breaker. The turbine-generator plant is operated by a hybrid control system having digital function capability during sequenced startup, synchronizing, load buildup and steady state load, and shutdown operations. The control system also contains monitoring and protective subsystems which function through all stages of operation, with redundancy and permissive features which maximize turbine availability.

US Classification:

60 3925

Abstract:

A local maintenance controller permits continued power generation during maintenance or failure of a primary gas turbine control system by manually for maintenance purposes or automatically for failure purposes assuming turbine control to thereby insure continued operation. The local maintenance controller set forth is particularly suitable for use in conjunction with a computer implemented gas turbine control system. Transfer between the local maintenance controller and the primary control system is effected in a bumpless manner so that load swings are absent. However, if the turbine was operating at system reserve at the time of transfer, the local maintenance controller reduces the load to peak value until primary control is resumed. Operation at any other load at the time of transfer is maintained by the controller. Transfer back to primary control is also effected in a bumpless manner.

International Classification:

H01P 104

US Classification:

333 24C

Abstract:

The present invention is directed to an electrical connector for blocking direct current while permitting transmission of alternating currents. The connector includes a first connector member and a second connector member for matingly receiving the first connector member. The first connector member includes a first conductor and the second connector member having a second conductor. The first and second conductors are positioned adjacent to one another and spaced apart by a layer of dielectric material. The dielectric material provides capacitive coupling of alternating currents from one conductor to the other while preventing coupling of direct current from one to the other. It is an object of the present invention to provide an improved electrical connector with an integral dielectric coating for direct current blockage.
